LESTER W. BOND, OF NEW YORK. N. Y., ASSIGNOR T0 BERBECKER 85'ROWLAND MlANU FAGTURING COMPANY, OF WATERVILLE, CONNECTICUT, A CORPORATION OF GON- I NEOTICUT.

To all whom-it may concern:

Be it known that I, LESTER; W. B'oNm'a. citizen of the United States, and a resident of New York, borough of Manhattan,- in the county of New York and State of New York, have made and invented certain new and useful Improvements in Extension- Rods, of which the following is a specification. 7

My invention relates toextension rods such-as are used for the support of curtains, draperies, etc.; one object of the present invention being to-construct the ends of the I telescoping rods so that, although the rods are'of different sizes allowing themtotelescope one within the other, they are adapted to-engage and'be supported by, brackets of uniform size, thus rendering "the extension rod reversible, end for end, and eliminating the use of right and left brackets.

.-A further object is to accomplish the aforementioned end by flattening-the extremity of the smaller rodof the telescoping pair, so that the majordiameter of the oval or ellipse as thus formed is the diameter of the end'of the other rod,thus rendering the rod reversible, end for end, and* allowing it to be secured to brackets ofuni form size and without resorting to the use of auxiliary sleeves or bushings.

A further ob ect is to 1 provide a novel bracket for use in connection wlth the cur-' 7 tain rod, as above outlined, which is simple j the attaching memberso formed that'a certain resiliency and spring will be incor-- porated therein, which will prevent the accidental detachment of the extension rod therefrom. y

Other objects'and as the description proceeds, wherein it is-to be understood, that changes in the precise embodiment of the invention can be made within the scope of what is claimed, Wllllih" out,,departing from the spirit thereof.

Figure 1-1sa view in top lan of'anextension rod embodyingthe characteristic fea-- tures of my invention. Fig.2 is a view in longitudinal vertical section of one end of the extension rod, and illustrating, in detail,

my novel supporting bracket therefor: Fig. 3 1s a view similar'to the above, illustrating the other and remote end of the extension rod. Fig. & is a view insection taken on the-line- M of Fig. 3. Fig. 5-is a view 1n section taken on the line 5-5 of'Fig. 2. F g. 6 1s a similar view taken on the line 66 of Fig. 3. Fig. 7 is a view in perspective of my novel supporting bracket. Fig. 8'is a view in front elevation of the supporting base of the bracket. Fig. 9 is a detail view in elevation of the wire supportingmember. F lg. 10 is a view in side elevation and partially in section of a modified form of bracket. in front elevationof the supporting base of thebracket, and Fig. 12 isa view of the wire loop, which is utilized in connection with the modified form of bracket. Fig. 13

is a view in perspective of a somewhat further modified form of bracket.

Referring specifically to the several views,

the curtain or extension rod is formed with the telescopic rods 15-16, the rod 15 being the smaller andslidably fitting within the rod 16, both of which are provided with the rightangle bends 17, so as to form the conventional goose-neck curtain rod.

I Theexposed extremity of the smaller'rod isfiattened, as illustrated in Fig. 6, so that an oval orelliptical end 18 is formed, the

major'axis of which,is substantially equal to the diameter-of the end 19 of the larger rod. A uniform sizeof bracket may accordinglybeutilized, doing away with the use oftwo sizesof brackets for the support of" Fig. 11 is a view each curtain ro'd and furthermore" rendering 1 the latter reversible.

' The preferred form of" bracket for use'in' connection with the extension rod, as above outlined, is illustrated in Figs. 2 to 9 inclusive, and is formed with thebase 20, through whichextends suitable openings21- for the reception of holding screws or analogous-.means', whereby the bracket-may be rigidly se'curedto a supporting structure. The base, which-is preferably stamped from receptacle, in which is inserted a supporting member 24, the same being preferably formed from a single length of wire, looped upon itself at "its middle, and which loop portion is reduced in size, by the action of suitable dies or analogous means, so that the supportingmember is provided with the securing end 25, the terminal of which is marked or defined by the shoulders 26. Theselshoulders bear against the endwalls of the hub or retaining member 23 and hold a the two in proper position during the time the securing member is being permanently attached tothe base nd ncreaslng the per manency of said attachment.

The. supporting member which is preferably formed of a single length of wire accordingly includes spaced sides, resiliently held apart and withthe'outer extremities thereof inwardly curved so that the supporting member will be provided with a rounded outer, end; By the action of suitable dies theside walls .27 of the; retaining member are compressedjagainst the sides of the fixed end 25 of the supporting member, resulting V in-the rigid connection of the two. This connection between the base and supporting i 1 member further strengthened by the heads 28 formed by upsetting the loop portion of the S supporting" member 1 which projects within the raised portionof the base, these heads bearing against the back of the base and'preventing the separation of the base and supporting member. ,The separated sidesof the supporting member .24 and their spaced endsembody acertain degree of resiliency so that after the extensionrod has beensecured to" the supporting brackets it will be rigidly soheldh 1 A somewhat modified form of bracket is disclosed in Figs; 10. to 12 inclusive, wherein thehub or :retain'i-ng member 29 is formed with the outer and apertured wall 30. The

supporting; memberi-33 "is -U-shaped and the ends; 32 thereof .are' passed through the apertures- 31 in the end wall of the retaining v memberandare providedwith the heads 36. Thejends'32 ofithe supporting member are somewhatreduced. in size edits to definethe shoulders 26;" which, in connection: with the heads 36, bear against the inner and outer portions of thea'base, and rigidly; connect and securerthe; supporting member-- thereto.

The sidewalls'ofitheretaining member 29 are compressed into; engagement. with the ends 32 of the supporting member," and fur- :tlier aid in tl ejsecurement .betweenthe two.

In both types ofbrackets, as thusdescribed, thefouterfand free extremity ofthe supporting member is of-rounded contour, facilitat-' ing the secure'ment' of the extension rod upon the brackets, which, having once been so assembled, are forcibly locked against detachment.

1 The bracket illustrated. in Fig. 13 is formed entirely of wire, rendering it extremely cheap to manufacture, and at the same time it is capable of performing efficient service. It is similar to the previously-described types of brackets, in that it includes a base 44 from which projects the wire supporting member 42. The supporting member is of loop-shape, and includes the spaced sides 41, with the restricted or bent extremities 43, which correspond to the shoulder-forming bends of the previously described supporting members. The base 44 includes the eyelets as which are adapted to receive suitable holding screws therethrough, whereby the bracket may be rigidly secured to ,a supporting structure. The base in this latter-mentioned type of bracket, and also the bases of the previously described brackets, are of greater length than, breadth, so that the spaced sides of the supporting member will be ordinarily placed in. vertical alinement,in which position they are adapted to withstand the greatest strains,

as will be readily appreciated.

'5. An article of theclass prising apair of hollow circular telescopic rods, the extremity of the small rod provided with anoval-shape end with the major axis thereof approximating the diameter of the end of thelarger rod, and brackets therefor-including relatively wide and thin supporting members.
